Taiwan tightens quarantine rules on arrivals from Brazil (2021/02/22)

A mutant COVID strain originating from Brazil is now in Taiwan. This variant type, called P1, was identified for the first time through genomic sequencing in three cases.
The P1 strain contains mutations that are believed to make it more transmissible and more able to fight currently available vaccines. Officials have announced stricter quarantine rules that will take effect on arrivals with a recent travel history to Brazil, starting Wednesday.

So far, Taiwan has had three cases of a new COVID variant originating from Brazil. In light of these cases, starting midnight on Wednesday, all arrivals from Brazil will be required to enter centralized quarantine centers, just as U.K. and South Africa arrivals are.

Philip Lo
CDC deputy director-general
The main issue is that it contains the N501Y mutation that is shared by both the U.K. and South African variants, indicating that it could have increased transmissibility. In addition, it has the E484K mutation already seen in the South African variant. That could affect vaccine effectiveness.

With mutations on the rise, there could soon be more highly contagious strains with the ability to evade vaccine defenses. A Swiss virologist warns that the world should get vaccinated fast to block the rise of more mutant variants. But a local infectious diseases expert says it's too soon to panic over mutations.

Huang Li-min
NTU Children's Hospital head
So far mutant strains haven't been too much a problem. The issue is limited mostly to South Africa, and we've only seen a slight reduction in vaccine effectiveness. So we still have to wait and see for awhile before we know the impact.

Lee Ping-ing
NTU Children's Hospital physician
I think that the concerns over mutant strains are a bit exaggerated. As a matter of fact, all coronaviruses and other RNA viruses, including the virus for measles and polio, are mutating all the time. Their mutations don't necessarily give rise to a new virus types that disarm vaccines.

The physician said there's no vaccine that protects against all strains. But if people keep washing their hands, wearing a mask, and maintaining their personal hygiene, there's no need for much alarm, even as mutations multiply.

台灣出現首起巴西變種病毒P1 傳播力強

台灣出現首起巴西變種病毒P1,指揮中心推測,和英國、南非變異株相比,P1會使病毒傳播力上升,疫苗效力下降,瑞士病毒學家甚至警告,未來變種病毒會越來越多,全球都應盡速接種疫苗。但台大兒童感染科醫師李秉穎認為,其他疾病病毒都在突變,應多加觀察,別太過恐慌。

台灣出現三起,巴西變種病毒感染者,因此2月24日零時起,和英國、南非一樣,從巴西入境者,都得住集中檢疫所。

[[疫情指揮中心醫療應變組副組長 羅一鈞]]
“主要是因為它帶有跟英國、南非都相同的N501Y,表示說它有可能傳播力會增加,那另外它也帶有跟南非變異株,相同的E484K這個突變,認為有可能影響疫苗的保護效果。”

對於變種病毒,導致傳播力增加,疫苗效力下降,瑞士科學家甚至警告,全球都應早點接種疫苗,以免未來變種病毒,越來越多,台灣的醫師則認為不用太恐慌 。

[[台大兒童醫院院長 黃立民]]
“目前變種病毒還沒有造成太大的問題,它只侷限在南非那一帶,而且它對疫苗的效果是小幅度的降低,所以你要再看一段時間,才會知道變種病毒的影響。”

[[台大兒童感染科醫師 李秉穎]]
“我想變種病毒的疑慮是有點言過其實了,事實上新冠病毒和其它所有RNA病毒,包括麻疹病毒、小兒麻痺病毒,都一直在突變,它們的突變不見得會變成一個新的病毒種類,然後讓我們的疫苗失效。”

台灣專家認為疫苗不是萬靈丹,只要勤洗手、戴口罩、維持個人衛生,就算病毒繼續變變變,也不用過度擔心。
